SUMMARY OF THE INVENTION

[0017] It is the object of the present invention to provide an exercise apparatus to exercise four groups of muscles.

[0018] It is another object of the present invention to exercise the abdominal muscles, the hamstring muscles, the maximus gluteus muscles and the quadriceps muscles.

[0019] It is yet another object of the present invention to provide an exercise apparatus that can be efficiently and economically manufactured.

[0020] Briefly, in accordance with the present invention there is provided an exercise apparatus that has a rectangular seat which is attached to a main rectangular member. The main rectangular member has fitted therein a rectangular footrest member having a attached thereto a tee footrest. The rectangular footrest member is longitudinally adjustable for different torsos sliding in the main rectangular member. The seat is also adjustable along the main rectangular member to adjust to different physical dimensions of an exerciser. The backrest is fastened to a backrest member that has an adjustable headrest on the upper end. Fastened to the bottom end of the backrest member are hand holds on each side. The backrest member is hinged to a link member on one end and the link member is hinged to an extension of the main rectangular member on the other end. The main rectangular member is divided into two members, terminating at a cross member fastened at the end of the two members. Fastened to the end of two members is a rod extending outward where one end of an elastomeric fitted on the rod, the other end of the elastomeric being fastened to a rod extending outward and attached to each side of the backrest member. Also attached to the upper side of the back rest member is a rod having attached thereto two flexible Webs have hand grips on one end to assist the exercise when performing the various exercises.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] Turning now to FIG. 1 there is seen an exercise apparatus generally shown as 10. The exercise apparatus 10 has a backrest 12 and a seat 14. The backrest 12 and seat 14 are made from a hard material such as wood or fiberglass covered by foam material and having an outside cover of waterproof material. The seat is attached to a main rectangular member 16 and the seat 14 is adjustable along the main rectangular member 16 to account for different physical dimensions of an exerciser. The push pin 15, as seen in FIG. 2 is provided for the longitudinal adjustment of the seat. The main rectangular member 16 has fitted thereon a rectangular footrest member (as seen FIG. 2 as 18) having attached thereto a tee configured footrest 20. The rectangular footrest member 18 is longitudinally adjustable by sliding inside the main rectangular member 16. This adjustment allows for various physical dimensions of the exerciser. The longitudinal adjustments for the footrest 20 is provided by pushpins 22 in the main rectangular member 16. The footrest 20 also folds down toward the rectangular member 16 utilizing a hinge provided by hinge pin 24. FIG. 1 also shows handles 26 and 28 that the exerciser holds with their hands when performing the leg exercises. This configuration is more readily shown in FIG. 7. FIG. 1 shows the extension of the main rectangular member 16 ending at cross member 30 that is provided for stability. Attached to the cross member 30 is a link bracket 32 that has pivoting means on one end for link member 34. The pivoting means is provided by pivot pin 36.

[0032] Turning now to FIG. 2 there is seen a left side view of the present invention. In this view there is seen the backrest 12 having a backrest member 37 with a headrest member 38 that slides in backrest member 37. The headrest member 38 has brackets 40 attached thereon and contains a circular padded headrest 42 which is covered with a waterproof material. The headrest 42 is adjustable by the headrest member 38 fitting into backrest member 37 and utilizing adjustment means 44. Also seen in this view is tension member 46. Tension member 46 fits on rods 48 and 50. The tension member 46 is held on rods 48 and 50 by retaining means which in this case are push pins 52 and 54. Also seen in FIG. 2 is a link bracket 35 that has pivoting means on one end for link member 34. The pivoting means is provided by pivot pin 39. Also in bracket 35 is locking pin 41. This locking pin 41 prevents the bracket 12 from rotating past a certain point as the locking pin 41 engages the link member 34 when the exerciser is performing the leg exercises. This condition is seen in FIG. 7. It should be noted that the present invention is supplied with a series of tension members having various tensions that can be fitted to the requirements of an exerciser. The tension members in the present invention are elastomerics. FIG. 2 also shows a bar 48 that is attached to headrest member 38. The flexible straps 52 and 54 are attached to bar 48.

[0033]FIG. 3 shows the headrest 42 and headrest member 48 with other exercise apparatus members that are described in FIGS. 1 and 2. FIG. 3 also shows footrest 20, seat 14, handles 26 and 28 and cross member 30. FIG. 3 shows the flexible straps 52 and 54 that have hand grips 56 and 58. The hand grips 52 and 58 assist the exerciser when performing the various exercises, specifically the abdominal exercises.

[0034]FIG. 4 shows a right side view of the present invention. It is essentially mirror of the present invention shown in FIG. 2. FIG. 4 shows the flexible straps 54 and hand grips 58. Also seen in FIG. 4 is tension member 60 fitted on rods 62 and 64. The tension member 60 is held on rods 62 and 64 by retaining means 66 and 68 which in this case are push pins.

[0035]FIG. 5 is a rear view of the present invention. FIG. 5 provides a good view of the two tension members 46 and 60. FIG. 5 also shows that bracket 35 is attached to main rectangular member 16. Bracket 35 also holds rods 50 and 64.

[0036]FIG. 6 is a view showing how the present is used to provide abdominal exercises. The exerciser sits on seat 14, places the back on backrest 12, places the feet on footrest 20, places the head on headrest 42, places the hands on hand grips 56 and 58 (not shown) and pulls forward with the hands and arms. This provides a resistance by tension members 46 and 60 (not shown) and the abdominal muscles are exercised. The exerciser relaxes and the tension member pulls the exerciser back to the original position. The exerciser repeats this movement until a complete abdominal exercise is accomplished.

[0037]FIG. 7 is a view showing how the present invention is used to provide leg exercises, namely, the hamstring muscles, the quadriceps muscle and the maximus gluteus muscle. The exerciser sits on seat 14, places the feet on footrest 20, places the back on backrest 12, places the head on headrest 42, places the hands on hand grips 26 and 28 (not shown) and pushes back with the back on the backrest 12 which lifts the exerciser's rear off the seat 14. The linking member 34 will rotate upward and locking pin 41 will present backrest 12 from rotating further since the locking pin 41 engages linking pin 34. This movement will in turn provide a resistance in tension members 46 and 60 (not shown) and exercise the leg muscles. The exercises relaxes and the tension members 46 and 60 will allow the exerciser to sit back on seat 14. The exerciser repeats this movement until a complete leg exercise is accomplished.

[0038]FIG. 8 shows the present invention in a collapsed position for storage.
